SPECIAL 45th Edition: HKS Super Turbo Ti Cat-Back Exhaust | 15-21 Subaru WRX & WRX STI (31029-AF013V)

Ordering the hks limited edition titanium exhaust for my S209 was super easy and convenient thru kamispeed! The communication and service was top notch and I even received it sooner than expected, I would highly recommend ordering thru them as a fully authorized hks distributer here in the US.

Awesome Service for ordering something this rare! A+++!!!

This is the second purchase I've made with Kamispeed. This purchase along with my 1st purchase has been a painless and headache free experience. All products arrived by their estimated shipment arrival dates and undamaged. The HKS build quality is what we all expect out of HKS - second to none. Fitment. Welds. Materials. However, I discovered an issue with the connection between the mid-pipe and the downpipe when installing this exhaust. The kit calls out for the use of the spherical "ball" style gasket and the spring tensioned fasteners used with the stock exhaust between the stock downpipe assembly and stock mid-pipe. Unfortunately, I've previously changed my downpipe (which is now flat-faced) and exhaust and dumped the stock hardware. I was able to re-use the hardware from my Tomei Expreme Ti cat-back exhaust and luckily had a spare flat-faced exhaust gasket to insert between my downpipe and the HKS exhaust. This HKS exhaust kit does not come with a new replacement spherical "ball" style gasket, flat faced gasket or hardware (spring tensioned bolts, general bolts, washers and nuts). So, if your plan is to use this exhaust with the stock downpipe, keep the stock fasteners to re-use and head down to your local Subaru dealership or Subaru parts page for a new spherical "ball" style exhaust gasket. If your plan is to use this exhaust with an after-market downpipe, you will need a new flat faced exhaust gasket and either you'll need to retain your hardware and re-use them or pick up some new bolts, washers and nuts. This is why my rating for this product is 4-stars. The completeness of the kit was disappointing for an exhaust that cost this much. Performance wise? If you want an aggressive exhaust note, this exhaust is not for you.. Turbo response feels good and I'm still hitting my target boosts levels on my Cobb tune. The STi is a lot LESS angry with the HKS exhaust and tunnel blasts aren't as exciting anymore but I've been told that at some point in your life, you have to grow up. I prefer to live in denial...
